I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.
Instructions
Cook the pasta according to the package directions. Drain and set aside.
In a saucepan over medium heat melt the butter, then whisk in the flour to make the roux. Allow to cook for 1 minute. Stirring occasionally to prevent burning.
Slowly whisk in ¼ of the milk, whisking continuously to prevent clumping. Then add in all of the milk and continue whisking until the milk thickens enough to coat the back of a spoon.
Whisk in the nutmeg, ground mustard, salt and pepper. Then whisk in the shredded cheese. Whisking continuously until the cheese has been fully incorporated. Remove from the heat. Adjust seasonings now, if needed.
Stir in the cooked pasta and half of the chopped bacon. Sprinkle the remaining bacon on top. Enjoy!
